nintendonite 

The mysterious element that all nintendo products except for the Nintendo Ds Lite and DSI and parts of the Wii are made of. This Element was discovered in an unknown location sometime before 1985 by poor asian techies. the reason nearly all nintendo systems were made of nintendonite was because NINTENDONITE IS THE STRONGEST PLASTIC PHYSICALLY POSSIBLE!

Nintendonite is not represented on the Periodic Table of Elements because releasing the details of Nintendonite's atomic structure would enable Microsoft and Sony to use it as well. That, or it could just as easily be that Nintendo doesn't even know... they're so innocent...

My Gamecube fell out of the plane when we landed but it still works fine except for the "open disc tray" button, but that's okay because you can pry it open. (yes, even the Gamecube was made of nintendonite. and yes, it could survive something like that)

or: my town was invaded by zombies but i threw my original gameboy at them and it was heavy enough to kill them. then i played super mario bros for a few hours.

or: i accidentally dropped my Gameboy SP in the garbage disposal, but it was closed and the water was off and it's made of nintendonite, so it's okay.

Dude, I played Final Fantasy for three days straight, but my Nintendonitis flared up so I couldn't play anymore.

Nintendonium 

The type of plastic famously used to make the Game Boy, the NES controller, and the SNES controller, among other Nintendo products. The substance is virturally unbreakable.

I took a hammer to my brother's Game Boy to get even, but I'm not strong enough to break Nintendonium.

Nintendoitis

Nintendoitis (noun) This condition usually occurs after you've played a console game too long. But was prominent with the original Nintendo Entertainment System back in 1985 with the original box controller. After many long hours of gameplay be it Zelda, Mario or Contra or whatever game you were playing, you would begin to feel pain in your thumbs and it would work its way up throughout your hand. But you usually wouldn't stop playing because you wanted to beat the game. But this condition can still occur with just about any game console controller.

Sam: Yo man I'm going to beat this PS3 game.
Tony: Ok I'll go watch a movie.
*three or four hours pass by Tony walks back into the room seeing Sam still at it.*
Tony: So how much further do you have to go in the game?
Sam: I'm almost finished but I'm developing a bad case of Nintendoitis.
